Astronomers have discovered the closest black hole to our solar system — it's just 1,000 light-years away.
Scientists from the European Southern Observatory (ESO) detailed the findings in a study published Wednesday in the journal Astronomy & Astrophysics.
Since black holes exert a force of gravity so strong that not even light can escape, you can't see them directly — but you can see some of the stuff that orbits them. That's how the researchers stumbled upon this black hole. They were studying double-star systems and noticed that one of the stars they were watching was orbiting an invisible object every 40 days.
